Shifting the given graph 4 units to the left, then 3 units up. b. Shifting the given graph 4 units to the right, then 3 units down. c. Shifting the given graph 4 units to the right, then 3 units up. d. Shifting the given graph 3 units to the right, then 4 units down.

Solution

To solve this, let's analyze the transformation of the function y=f(x)y = f(x) into y=f(x4)+3y = f(x - 4) + 3.

  1. Transformation of xx to x4x - 4:

    • When we replace xx with x4x - 4, this results in a horizontal shift of the graph.
    • The graph is shifted 4 units to the right. This is because when the input xx is decreased by 4 (i.e., x4x - 4), the function is "delayed" by 4 units, meaning each point on the graph moves to the right by 4 units.
  2. Transformation of the function to f(x)4+3f(x) - 4 + 3 (or +3+ 3):

    • Adding a constant (like +3) outside the function shifts the graph vertically.
    • The graph is shifted 3 units up, as adding a constant to the function increases its output for every input.

Thus, the transformation involves a shift of 4 units to the right and 3 units up.

The correct answer is:

c. Shifting the given graph 4 units to the right, then 3 units up.


Would you like more details on transformations of functions, or do you have other questions? Here are some related questions to explore:

  1. How does the graph of y=f(x+4)y = f(x + 4) compare to the graph of y=f(x)y = f(x)?
  2. What happens when you shift a graph horizontally and vertically simultaneously?
  3. Can transformations like this be applied to trigonometric functions like y=sin(x)y = \sin(x)?
  4. How do reflections across the x-axis or y-axis affect the graph of a function?
  5. How would you interpret the transformation y=f(x+2)5y = f(x + 2) - 5?

Tip: When analyzing transformations, remember that a change to xx affects horizontal movement, while changes to the function (like adding or subtracting constants) affect vertical shifts.
